What is the correct terminology for servers that require a larger than normal percentage of “on time”.
For starters I am not a windows admin, so I am trying to understand counter concerns from a windows admin on some issues. But I have noticed a lot of our windows servers are on an unsupported service pack. These seem to be more important servers for critical apps. There is definitely a trend. I am wondering why they may be on an unsupported SP. Does applying an SP take more effort and more down time than normal monthly patches?
What should an admin do when applying an SP to a server that does not have much of a window for down time? Or are there no such servers – every server has a window of opportunity when it can be patched/SP’d.
Do normal patches require reboots?
I was thinking for stuff like banking apps (which doesn’t apply in our case) where users are accessing them 24/7 – what do there admins do when it comes to patching / applying SP’s?
